0x42000801 is not defined in reader.h

Your conversion function can be generalized.
control_code = (control_code & 0x3ffc) >> 2;
control_code = SCARD_CTL_CODE(control_code);

The only documented control code I know is:
#define CM_IOCTL_GET_FEATURE_REQUEST SCARD_CTL_CODE(3400)


> 0x00313520 is equivalent to 0x42000801 ( 3400 - GET_FEATURE_REQUEST)

???

Maybe it is a proprietary code for your Windows driver and/or application.
